Chopin’s Étude No.3 in E Major, Op. 10 “Tristesse” (performed by Lang Lang)
"Chopin was said to have noted this piece as the most intimate he had ever composed, stating that 'In all my life I have never again been able to find such a beautiful melody.' This Etude has also been known as ‘Tristesse’, meaning ‘Sadness’ in French.”
[…] there’s something kind of timelessly vital and sacred about good writing. This thing doesn’t have that much to do with talent, even glittering talent… Talent’s just an instrument. It’s like having a pen that works instead of one that doesn’t. I’m not saying I’m able to work consistently out of that premise, but it seems like the big distinction between good art and so-so art lies somewhere in the art’s heart’s purpose, the agenda of the consciousness behind the text. It’s got something to do with love. With having the discipline to talk out of that part or yourself that can love instead of the part that just wants to be loved.
—David Foster Wallace (via sometimesagreatnotion)
Computers are providing solutions to math problems that we can’t check
Good news! A computer has solved the longstanding Erdős discrepancy problem! Trouble is, we have no idea what it’s talking about — because the solution, which is as long as all of Wikipedia’s pages combined, is far too voluminous for us puny humans to confirm.
A few years ago, the mathematician Steven Strogatz predicted that it wouldn’t be too much longer before computer-assisted solutions to math problems will be beyond human comprehension. Well, we’re pretty much there. In this case, it’s an answer produced by a computer that was hammering away at the Erdős discrepancy problem.
